FIGURE 3 in Devonian smooth-walled tasmanids and new insights of life-cycle descriptions through fluorescence microscopy

FIGURE 3. Transmitted and incident light images of silica-rich microspherules retrieved from the Oatka Creek Formation, Leroy, New York. 1a–c conjoined or splitting tasmanid containing internal pyritic inclusions, interpreted to be a dividing cyst; 2a–c single tasmanid with no pyritic inclusions but numerous surficial punctae, interpreted to be a vegetative cyst; 3a–c tasmanid with well defined internal structure interpreted to be a resting cyst. Images taken at a magnification of 10x, average diameter of all cysts, 125 µm.
